The pressurized water tank is the main water tank used by the manufacturers of automatic feeding mixer at present. Most of these water tanks are made of steel because they bear certain pressure. Generally, the cylinder is made of 3 ~ 4mm Q235 steel plate, and the head is made of 4 ~ 5mm Q235 steel plate or 4mm Q235 steel plate. Its interior is easy to rust and needs coating protection, but at present, most manufacturers do not do anti-corrosion treatment in order to reduce costs.

如何自动上料搅拌车钢制水箱的锈蚀问题及不同材质的水箱有哪些优缺点？(图1)

How to solve the corrosion problem of steel water tank of automatic feeding mixer truck and what are the advantages and disadvantages of water tanks of different materials? (Figure 1)

从技术角度考虑，我认为主承压水箱为目前自动上料搅拌车生产厂家主有两个途径锈蚀问题。

From a technical point of view, I think the main pressure water tank is the main manufacturer of automatic feeding mixer truck, and there are two ways to solve the corrosion problem.

一是从现有产品的工艺加工和质量控制上考虑，如镀锌处理，较适合追求低成本的汽车厂家，工艺灵活，产品改型也较容易。然而电镀的缺点也较多，工艺要求严格，产品质量控制困难，特别是焊接处锈蚀仍不好处理，等等。如果采用浸镀工艺，成本更高。自动上料搅拌车

First, considering the process processing and quality control of existing products, such as galvanized treatment, it is more suitable for automobile manufacturers pursuing low cost, with flexible process and easy product modification. However, electroplating has many disadvantages, strict process requirements, difficult product quality control, especially the corrosion of welding joint is still difficult to deal with, and so on. If the dip coating process is adopted, the cost is higher. Automatic feeding mixer

二是从产品的材料上考虑。目前可替代的材料主要有不锈钢、塑料 含玻璃钢 和铝合金等。这几种材料都能够完全产品的锈蚀问题，但由于每种材料的加工工艺不同，又都存在着各自的优缺点。自动上料搅拌车

Second, consider the material of the product. At present, the replaceable materials mainly include stainless steel, plastic, including FRP and aluminum alloy. These materials can completely solve the corrosion problem of products, but due to the different processing technology of each material, they all have their own advantages and disadvantages.

钢制水箱适用于气压式供水，制作简易、维修方便。 年前有企业采用配水泵使用的玻璃钢水箱，较便宜、质量轻，不易生锈。但缺点是易破碎，不易修，且不适宜气压式供水。塑料水箱目前多用于客车上的饮用车载水箱和卡车上，其质量轻、，强度也较高，开始有向工程车上推广使用的趋势。塑料箱体本身的承压应能满足要求，但接头部分的密封要处理好，好配水泵使用。还应做低温脆性的防护处理，但这样会增加生产成本。

The steel water tank is suitable for pneumatic water supply, with simple manufacture and convenient maintenance. Years ago, some enterprises used FRP water tanks for water distribution pumps, which are cheap, light and not easy to rust. But the disadvantage is that it is easy to break, difficult to repair, and not suitable for pneumatic water supply. At present, plastic water tanks are mostly used in drinking water tanks on passenger cars and trucks. They are light, environmentally friendly and have high strength. They begin to be popularized to engineering vehicles. The pressure bearing of the plastic box itself shall meet the requirements, but the sealing of the joint part shall be handled well for the use of the water distribution pump. The protection treatment of low-temperature brittleness should also be done, but this will increase the production cost.
